Mobile devices are relatively fragile when compared to desktops and laptops and, while it is important to back up all data, it is especially important to back up these devices. Luckily, you can back up the data on your Android device via your Google account or backup and restore on your phone.

Tap on the refresh icon. The icon is located to the left of your Google account. Tapping on it will cause your apps to sync to the Google account you're signed into. All of the selected apps will be backed up.

The sync should automatically happen when you open this menu, but you can ensure that your backup is up-to-date by tapping on the refresh icon.

Tap on the Settings app. The icon for the Settings app resembles a gear, and is usually located on your home screen but can also be found in your apps menu. The Settings menu contains a "Backup and Reset" options, which allows you to backup the factory default apps on your phone like Email and Messages.
